Alpha human atrial natriuretic polypeptide (alpha-hANP) was intravenously infused into 7 patients with ischemic heart disease who had almost normal cardiac function at a rate of 0.025 micrograms/kg/min for 15 min. During infusion of alpha-hANP, left ventricular (LV) systolic pressure decreased from 144 +/- 19 (SD) to 129 +/- 22 mmHg (p less than 0.01), LV end diastolic pressure (EDP) from 15 +/- 5 to 13 +/- 4 mmHg (p less than 0.05), mean aortic pressure from 102 +/- 14 to 91 +/- 14 mmHg (p less than 0.01), time constant of LV pressure fall (T) from 100 +/- 15 to 88 +/- 13 msec (p less than 0.05), systemic vascular resistance (SVR) from 1711 +/- 206 to 1424 +/- 340 dynes.sec.cm-5 (p less than 0.05) and coronary vascular resistance (CVR) from 8.5 +/- 1.2 to 7.4 +/- 1.3 x 10(4) dynes.sec.cm-5 (p less than 0.05). There was a linear correlation between percent changes in SVR and those of CVR (r = 0.92, p less than 0.01), and the fall in CVR was approximately 68% of that in SVR. Increases occurred in heart rate from 63 +/- 7 to 66 +/- 8 beats/min (p less than 0.05), LV dp/dt from 1558 +/- 266 to 1627 +/- 238 mmHg/sec (p less than 0.05), LV dp/dt/p from 22.9 +/- 3.2 to 25.6 +/- 3.7/sec (p less than 0.01), and myocardial oxygen consumption (from 7.9 +/- 2.4 to 9.8 +/- 2.1 ml/min, p less than 0.05), while mean right atrial and mean pulmonary arterial pressures and pulmonary vascular resistance were unchanged.(ABSTRACT TRUNCATED AT 250 WORDS)
